But life doesn't always run smoothly and it only takes one slip up to turn your 0% "loan" into 35% revolving debt.If you honestly believe you have the discipline/intelligence necessary to maintain the balancing act, then more power to you, but why take this risk when alternative financing sources are so cheap these days?  

I believe there are two strategies that both work well to investing profitably in real estate.The first revolves around you.

2) somehow use revolving credit from the equity in the house? 

@Cam Clinger If the home is older, you should assume that its going to be a 2 ton unit.  

Essentially they use revolving lines of credit, with fees for liquidating to cash.

Because it is a revolving line, I am free to put everything I make/already have into the HELOC to reduce accruing interest and can then take it out later if I want to use it.An easy way to look at it would be if you have $100K in savings and a $100K mortgage. 

Essential everything revolves around a few simle things.

I was in a similar place at your age, building a business that did not revolve around my passions or an area where my core knowledge and genius existed.

Let me pose this question, how many people on here give back to their communities, have you donated some sweat equity, give some money to a charity, even said a kind word to a homeless guy/ gal on the street.My personal opinion is that these political parties are set up to keep people under control and thats it.... everyone was so happy and filled with hope for obama now he's going to be the death of our america; there is no our america its is and always will be changing; john f. kennedy faced hell to get elected because he was catholic and it was though he was going to be taking orders from the pope, now he's looked back on with rose tinted glasses.People fight so hard against education and understanding the world outside of their little box; i've seen programs where people would shout burn the books but leave our bible alone; people still thinks the sun revolves around the earth, or don't know where the sun goes at night. . . its not about democrats or republicans i'm sure most of you guys know that those parties basically flipped during the civil rights era; i often hear people say were the party of abraham lincoln really what does that mean, in todays world it means nothing!
